E-M:/ Monday Ozone Episode in Benzonia/Ontario Smog Alert

Enviro-Mich message from "Alex J. Sagady & Associates" <ajs@sagady.com>

The first smog alert of the season comes not from
MDEQ but from the Ontario Ministry of the Environment.  (See below
for Ontario smog alert for Thursday)

Ontario health standards for ozone
are more stringent than even the new
ozone standards in the US.....  [Ontario 0.08 ppm, 1 hour average;
U.S.  85 ppb, 8 hour average]   In fact, this old-timer can remember when 
the US standard was the same as the Ontario standard before Jimmy Carter 
changed it in 1976.

MDEQ has not issued any ozone alerts yet this season.

However, MDEQ's web site is showing the first excursion
in Michigan for 2001 over the level of the 8 hour health standard occurred 
Monday in Benzonia, MI with 87 ppb, 8 hour average.

At 2 PM today, the highest 1 hour ozone reading is in
Port Huron (Just across from Sarnia which is in the
Ontario alert region) with 73 ppb.

Yesterday, Benzonia hit 90, 1 hr average and Scottville hit
91, 1 hr average.

Current 1 hr ozone readings are at:


Current 8 hour average readings at:

symptoms such as coughing or shortness of breath. People
with heart or lung disease including asthma may experience
a worsening of their condition.

* An Smog Advisory means that there is a strong likelihood
that there may be poor air quality within the next 24 hours
due to ground-level ozone and particulate matter.
